SMA6851M

SMA6850M Series High Voltage 3-Phase Motor Drivers Features and Benefits ▪ Built-in pre-drive IC ▪ MOSFET power element ▪ CMOS compatible input (5 V) ▪ High-side gate driver using bootstrap circuit or floating power supply ▪ Built-in protection circuit for controlling power supply voltage drop ▪ Built-in overtemperature detection circuit (TD) ▪ Output of fault signal during operation of protection circuits ▪ Output current 1.5, 2, and 2.5 A ▪ Small SIP (SMA 24-pin) Packages: Power SIP Not to scale Leadform 2451 Leadform 2452 Description The SMA6850M inverter power module (IPM) series provides a robust, highly-integrated solution for optimally controlling 3-phase motor power inverter systems and variable speed control systems used in energy-conserving designs to drive motors of residential and commercial appliances. These ICs take 230 VAC input voltage, and up to 2.5 A (continuous) output current. They can withstand voltages of up to 500 V (MOSFET breakdown voltage). The SMA6850M power package includes an IC with all of the necessary power elements (six MOSFETs), pre-driver ICs (two), and flyback diodes (six), needed to configure the main circuit of an inverter. This enables the main circuit of the inverter to be configured with fewer external components than traditional designs. Applications include residential white goods (home applications) and commercial appliance motor control: Air conditioner fan Small ventilation fan Dishwasher pump Functional Block Diagram ...
